Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BGA3015,115 are evaluated based on the following critical parameters that determine functional compatibility:

Package Compatibility: All substitute parts must use the TO-243AA package (SOT-89 variant) to ensure mechanical and electrical pin compatibility with existing PCB layouts.

Frequency Coverage: The BGA3015,115 operates from 5MHz to 1GHz. Substitute parts must support this frequency range or provide broader coverage that encompasses the CATV band.

Electrical Performance: Gain, P1dB, and noise figure are primary performance metrics. Substitutes must maintain comparable or superior performance characteristics to ensure signal integrity in CATV applications.

Supply Voltage Compatibility: The BGA3015,115 accepts 5V to 8V supply. Substitute parts must operate within or overlap this voltage range.

Mounting and Environmental Compliance: All parts must be surface-mount components with ROHS3 compliance and MSL rating of 1 or better.

The substitute parts identified (HMC311ST89E, HMC311ST89ETR, HMC480ST89E, HMC480ST89ETR) meet these criteria with the following distinctions:

• HMC311 Series: General-purpose RF amplifiers with broader frequency coverage (0Hz ~ 6GHz) but lower P1dB (13dBm) and higher noise figure (5dB)
• HMC480 Series: General-purpose RF amplifiers with frequency coverage to 5GHz, higher P1dB (20dBm), and lower noise figure (4dB), representing superior performance in the upper frequency range

Parameter Comparison

Engineering Selection Recommendations

For CATV-Specific Applications (5MHz ~ 1GHz):

The HMC480ST89E and HMC480ST89ETR are the preferred substitutes when operating within the CATV frequency band. These parts provide superior P1dB (20dBm vs. 18dBm) and lower noise figure (4dB vs. 2.6dB), delivering enhanced linearity and signal quality. Both variants are in Active product status with full ROHS3 compliance and MSL-1 ratings, ensuring long-term availability and environmental compliance.

For Extended Frequency Coverage:

The HMC311ST89E and HMC311ST89ETR offer broader frequency coverage (0Hz ~ 6GHz) suitable for applications requiring operation beyond the CATV band. However, these parts exhibit lower P1dB (13dBm) and higher noise figure (5dB), which may impact performance in high-power or low-noise-critical applications. Both are Active products with ROHS3 compliance.

Supply Voltage Considerations:

The HMC311 series operates at 5V only, while the HMC480 series and original BGA3015,115 support 5V to 8V. Applications utilizing higher supply voltages must select HMC480 variants or confirm 5V operation compatibility for HMC311 parts.

Packaging and Availability:

All substitute parts use identical TO-243AA (SOT-89) packaging, ensuring direct PCB compatibility. HMC480ST89ETR shows the highest inventory availability (61,931 pcs), followed by HMC311ST89ETR (15,975 pcs), supporting volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can HMC311 and HMC480 series parts be used interchangeably with BGA3015,115?

A: Both series are mechanically compatible (TO-243AA package, surface mount) and electrically compatible within the 5MHz to 1GHz CATV band. However, electrical performance differs. HMC480 series provides closer performance matching (P1dB 20dBm vs. 18dBm original), while HMC311 series offers broader frequency coverage at the cost of lower P1dB and higher noise figure.

Q: What is the impact of noise figure differences between BGA3015,115 (2.6dB) and substitute parts?

A: The BGA3015,115 exhibits superior noise performance (2.6dB). HMC480 series (4dB) represents a 1.4dB degradation, while HMC311 series (5dB) represents a 2.4dB degradation. In low-signal applications, this may require circuit-level compensation or gain adjustment.

Q: Are there supply voltage restrictions when substituting?

A: Yes. HMC311 parts operate at 5V only, while HMC480 parts and the original BGA3015,115 support 5V to 8V. Designs using 6V to 8V supply must use HMC480 variants or confirm 5V operation for HMC311 parts.

Q: What is the difference between HMC480ST89E and HMC480ST89ETR?

A: Both parts are electrically identical with identical electrical specifications. The primary difference is packaging: HMC480ST89E is supplied in Strip packaging, while HMC480ST89ETR is supplied in Bulk packaging. Selection depends on production volume and handling requirements.

Q: Is the BGA3015,115 still available for new designs?

A: No. The BGA3015,115 is classified as Last Time Buy, indicating production discontinuation. New designs should select from the Active substitute parts (HMC311 or HMC480 series) to ensure long-term supply chain continuity.

Q: Do all substitute parts meet ROHS3 compliance?

A: HMC480ST89E and HMC311ST89E are confirmed ROHS3 compliant. HMC480ST89ETR and HMC311ST89ETR do not have specified RoHS status in the provided data. Compliance verification with the manufacturer is recommended for applications with strict environmental requirements.
